3-port Filter WDM based on thin-film filter technology, which are available on ITU channel spacing of 100GHz/200GHz CWDM spacing. These thin film filter products utilize hermetic and epoxy-free optical path technology to provide excellent performance and reliability.

Coarse Wavelength Division Multiplexer (CWDM) is based on thin film filter technology. Yilut provides package options and integration for customized request.

Dense Wavelength Division Multiplexing(DWDM) is a Technology That Puts Data Different Sources Together on an Optical Fiber, with Each Signal Carried at the Same Time on Its Own Separate Light Wavelength.

The CWDM/DWDM Optical Add Drop (OADM) is designed to Add Drop multiple channels onto one or two fibers. And OADM is the ideal solution for the increasing bandwidth demand on enterprise and metro access networks

40ch-96ch Athermal AWG(Arrayed Waveguide Gratings) is a high performance DWDM mux/demux product based on planar lightwave circuit technology.

AWG CWDM4 Mux&Demux are PLC aligned units designed for high speed optical transceiver 100G+ GQSFP functioning as signal transmission and receive.
